Intermittent fault

[solid43]

Hi, my 2006 x-type 2.2d has just developed an intermittent fault when driving.

The sat nav display and radio & mainbeam switch off then the battery light and airbag light come on as if something has reset.

I also here a relay clicking from the passenger fuse box around the same time. Once it starts it occurs often.

I have tried reading fault codes but none come up. Does anyone have any ideas where I should start looking?

Hi Darryl

 

It sounds to me that your battery  is about to go --A Jaguar starts to shut things down to save the

charge to start the engine ,so first thing I would do is to get it checked.

I had a problem for a week with door lock and lights coming on at odd times then one morning no start ==Battery dead==

Fitted new and everything perfect.??

Hi Darryl, and welcome to the club.

 

Frank is quite correct.

 

The computer will shut down what it thinks you don't need!

 

Regards,

Many Thanks gents, I will take the battery to be tested. I hope it will be as simple as that.

I think I read to buy the jag battery's, any truth in this

If you have to have a new battery get the heavy duty the one that fits the case

not a cheapy because it will last longer with out problems.??

Go to  Halfords and get the 15% discount + they are very helpful and will give  advice

for the best one.

Hi Gents,

      I dropped in a new Bosch battery from Halfords this morning. took the old girl on a long drive and I am still seeing the same issue.

any other ideas what it might be

Hi Darryl

 

Sorry to hear that it did'nt cure things --The next thing I think you should check is all  Earth wires .???

Because a bad earth could be the problem .??

I would also try to find out which relay is clicking because that is perhaps faulty or has a loose wire.???

Hi Darryl, being an electrical engineer I would normally stress that 80/90 per cent of electrical faults on DC circuitry would be down to the earthing although having read through the posts, I agree with Frank on this one. Locate the relay and ensure its changing over when voltage is applied to the coil.
